[Feature] Filter out emojis that cannot be displayed on iOS

[naamapps]

Hi,
Thanks for the great package.
I was wondering if it's possible to filter out unsupported emojis on iOS.
I know it's currently only for android. But there is not reason why.

Please consider adding it to the package,
Thanks!

iOS doesn't provide an easy way to determine which emoji is supported or not like Android does. Beside that all emoji should be supported by iOS. Is there anything that doesn't work?

@Fintasys Thanks for your super quick response!
Well for older iOS versions not all emojis are supported (which is to be expected).
I hope we can come up with a workaround, because looking at question marks is super bad UX.
See iOS 15.3.1:

It's seems the issue is related to flutter.
Several issue are still opened:

• Heart suit emoji looks incorrect in iOS text field. flutter/flutter#49627
• Emoji Keycap Sequence not supported on iOS flutter/flutter#36062

I tried to check but there is no easy way to detect this glitch.
We have also this option checkPlatformCompatibility but it seems is still displaying the unsupported emojis :)

Any idea?

@Fintasys I found a good workaround. No more glitch :)
Regarding this comment: flutter/flutter#49627 (comment)

We can have this config (maybe it could be nice to have it by default in your package)

config: const Config(
  emojiTextStyle: TextStyle(
    fontFamilyFallback: [
      'Apple Color Emoji',
      'Noto Color Emoji',
    ],
  ),
),

On my side I've surrounded with my theme the fontFamilyFallback (to well display also on text field/content and so)

@stact thanks for sharing the workaround ! Seems Someone else created a PR to fix this issue more permanently, I will look into it. #172
